Resolution

• Configuring Pricing cards:

VM Pricing in Aria Operations is established based on either Cost (what it costs the business to run) or Rate (what you charge the consumer).

To define these values, navigate to:

Configure > Cost Settings > Pricing

From here, you can create a Pricing Card and assign it to specific vCenters, Clusters, or Tags.

• The Pricing Formula:

Aria Operations calculates the price by aggregating the individual rates for CPU, Memory, and Storage.

Total Monthly Price Formula:

Total Monthly Price = (vCPU * Rate) + (RAM{GB} * Rate) + (Storage{GB} * Rate)

• Calculate Daily Price:
  • Daily Price = Total Monthly Price / (Number of days in a Month)

 

Sample calculation:

• Consider a VM with the following configuration and assigned rates for a 28-day month (February):

Resource	VM Configuration	Assigned Rate
vCPU	16 vCPUs	3.68 per vCPU
Memory	32 GB	2.51 per GB
Storage	1.27 TB	0.16 per GB

 

 

• Step 1: Calculate Monthly Totals

• • vCPU: 16 * 3.68 = 58.88

  • Memory: 32 * 2.51 = 80.32

  • Storage: 1270GB (approx) * 0.16 = 208.07                     

• Step 2: Sum for Monthly Price

• • • 58.88 + 80.32 + 208.07 = 347.27

• Step 3: Calculate Daily Price
  • To find the daily rate for the current month:

347.27 / 28days= 12.40
